I work from home and got sick of working off a tiny laptop screen (as much as I love my Surface Book) so I decided to go big AND go home!
This is my first build in six years so it was huge upgrade over my GTX 660 / i5 3350P and my first foray into RGB. I wasn't sure how much I wanted or didn't want it, but knew I'd rather have it and turn it off than not have it and want it. The cable management for so many fans and so much lighting was pretty challenging even with the ample space for it in the H700i.
At work I'll need access to multiple virtual machines locally, so having a huge core count and tons of memory was a no-brainer pick for the Ryzen 9 3900x, and going big on the 16gb DIMMs for an eventual 64gb bank to run the VMs well. I also jumped into Xbox Game Pass for PC (24 months for a dollar!) so I needed a machine I could take advantage of that with.
And finally, new monitors. I had some Acer 23" touchscreen monitors (I thought Windows 8 touch would be great on desktop... whoops) that were great, but were only 1080p / 60hz and had horrible glare. So it was time to upgrade to 27", 1440p / 144hz with adaptive sync for all the screen real estate my desk could handle.
